Abstract:
Disclosed herein is a rotor permanent magnet apparatus for a drive motor based on temperature distribution. The permanent magnet may enhance coercivity without a substantial decrease in magnetic flux density Br by applying a grain boundary diffusion process of diffusing dysprosium on the surface of the permanent magnet based on the temperature distribution of the permanent magnet.
